MOLD FOR. FORMING THE LOWER SECTIONS OF MANSARD ROOFS UPON BUILDINGS.

Specification of Letters Patent.

Application filed Itenruary 24, 1914. Serial No. 820,527.

. To all whom it may concern:

Be it known that I, MARTIN GEORGE GAMB- SKY, a citizen of the United States, residing at Menasha, in the county of Winnebagoand State of \Visconsin, have invented a new and useful Improvement in Molds for Forming the Lower Sections of Mansard Roofs Upon Buildings, of which the following is a specification.

My invention relates to a Mansard roof for buildings, and is particularly adapted for silos, but it evidently can be used upon other buildings in which the walls are formed of cement, concrete, brick, &c., a but will be shown as applied to a silo and described as i so applied, and is designed for molding the steeper part of a Mansard roof, the advantages of which over the usual roof being that several feet in height are added to the capacity of the building and a better architectural design presented, while the increased cost is but little. The molds are made in sections and bolted together for use, the band molds for the wall of the building, the cornice supporting shelf and the in and tions each, and the mold plates for the inclined roof in a greater number of sections,

but no particular number are essential, they both the outer edge of the cornice shelf and the upper edge of the inner band mold, all of which are best formed of sheet metal, angle and other shaped irons, a ring being arranged at the upper ends of the roof mold plates, both insideand outside thereof, the

inclinedpart of the roof, all of which parts are shown in the accompanying drawing, in which- Figure l is a plan, which at the left hand section of the band mold shows the upper mold bands between which the main wall of the silo has been built up and is filled with cement, the two sections at the right showing bands mounted upon the first named bands but not yet filled w th cement, the

outer ones being each provided with a pluporting shelf in position upon the brackets- Fig. 2 is a side elevation of the outside of one of the outer band sections. Fig. 8 is a side elevation of the inside of one of the inside band sections. Fig. 4 is a complete vertical section of a Mansard roof. Fig. 5 is an elevation of the outside of one of the outer tapering sections which forms the outer mold plate for the roof. Fig. 6 is a section of said mold plate upon the line a, a; of Fig. 5. Fig. 7 is an elevation of the inside of one of the inner tapering sections which forms the inner mold plate for the roof. Fig. 8 is asection of said mold plate upon the line b, b, of Fig. 7. Fig. 9 is an elevation partly in section, of the inner and outer tapering mold plates upon the line 0, 0, of Fig. 18, mounted upon their respective band molds. Fig. 10 is an elevation of abracket for supporting the cornice shelf. Fig. 11 is a modification in the form of the bracket. Fig. 12 is an elevation of an inside tapering mold plate section, mounted in position upon the inner band mold, said band mold being mounted upon the upper mold piece of the Fig. 1G is an elevation of the outer ring at the top of the tapering mold platesand showing the manner of connecting the several sections thereof. Fig. 17 is a plan of the inside tapering mold plates in position around a silo with the corniceshelf in posi-, tion for receiving the outer tapering mold plates. Fig. 18 is a plan of the outer taperi g mold plates in position around a silo. Figs. 1. 4, 17 and 18, are upon a smaller scale than the others.

Similar numerals and letters indicate like parts inthe several views.

1, indicates the wall of a building formed of cement fonuse as a silo: 2 and 3. the outer and inner molds between which thcwall was formed .in a well known manner: and 5, are outer and inner mold bands of my invention, formed in sect ons as has been described, the outer band sections 4, having each a plurality. of loops (5, 1 for receiving Patented Dec. 8, 1914..

brackets 7 or 7 and which extend above the bands 1 and 5 for supporting a cornice shelf 8, and each inside band section 5, is provided with a plurality of bars which form fingers 9, that extend above the upper edge of said band for assisting in holding the tapering mold plates in position upon the band mold 5. The loops 6 may be secured to the plates, which inclose the outside of the roof,

in position- The tapering niol'd plates may all, both for the outer and inner side of the wall be of substantially the same taper, length and width, but more of them will be required for the outer than for the inner side of the, wall. Both the outer and inner plates 11 and 12, are provided along their tapering edges with flanges. which flanges may be of angle iron 13, and be provided with a pluralitv of holes 14, for receiving connecting bolts 15, as in Fig. 12, the bolts through the flanges of the outside tapering mold plates in Fig. 18' showing but one for want of space thereon. Around the top of the inner tapering mold plates a ring 16, ismounted upon the flanges 13. for preserving a circular form to the roof, as is shown in Figs. 9 and 17. and arranged upon the outer mold plates is a ring 17. formed of angle iron with one of the legs of the angle outwardly and verticallv arranged and serving as a shelf upon which to form a cornice for the upper and less inclined part of the roof. The inner tapering mold plates are each provided with an angle iron rib 18, which is secured to it longitudinally thereof and has at its lower end a finger 18*, which extends downward on to the band mold 5,'and in connection with the fingers 9 upon said band retain the tapering mol'd'plate upon the band 5. For spacing the'upper ends of the outer tapering mold plates from the inner ones, the outer ends of the brackets are provided with a perforation 20, (see the ends 18 and 19, Figs. 10 and 11), for receiving a wire or small rod, as 21, in Fig. 11. The upper end of the rodis formed into a hook and is hooked over the upper edge of the tapering mold plate and by swinging it to the right and left along said upper edge, the distance between the bracket end and tapering mold plate top can be changed, within certain limits, as is shown in dotted lines, upon one in Fig. 18', that is applied to a T bracket 7. A preferable method is shown in the use of the brackets 7 of Fig. 10; In this casea rod 21., is threadedand provided with a nut 22, the threaded end passed through the perforation 20, and its upper hooked end hooked over the upper edge of a tapering mold plate. V

By screwing the nut on and off the mold plate can be swung inward or outward as. the case demands with reference to the inner Inold plates. The two rings are made in sections for convenience in transportation and storage and the several sections canbe' connected by bolting a piece as 23, in Fig. 16, to adjoining ends. The cornice shelf sections are each provided with a tongue 2%, and socket 25, which may be of sheet metal and be soldered to the main sheet, the tongue being fitted to enter the socket and hold th two ends in position.

In Fig. 18, the position of the ring 16', is shown in dotted lines, the inner tapering mold plates not being shown in said figure.

In Figs. 1, 4., 9 and 17, the cement filling is indicated by 26. In Fig. 4-, the additional cement filling which is made with theuse of my" band molds is indicated by a, the cornice of the lower section of the Mansard roof by b. the less inclined part of the roof bv c, and the cornice for the upper and more inclined part by cl. After the molds have been filled and the roof completed up to the i cornice (Z, the balance of the roof can be formed with molds already in use, in a well known manner.

Having described my invention, what I claim and desire to secure by Letters Patent, 1

1. In a mold for the lower section of a Mansard roof for a building, an outer and inner band mold around the upper end of the building wall adapted to be supported upon the molds between which the wall was" formed, a plurality of brackets upon the outer band molds, a perforation through the outer end of each bracket. a cornice forming shelf mounted around said outer band mold upon said brackets having an upstanding rimaround its outer circumference, a plurality of tapering mold plates. each having means for securing one'to the other, ar-

ranged around the outer edge of the cornice forming shelf and within the upstanding rim aforesaid, a rodconnecting the upper edge of a tapering moldplatewith a bracket, and a plurality of like tapering mold plates as said outer ones aforesaid, mounted upon the upper edge of the inner band mold and a ring around their upper ends inside thereof.

2. In a mold for the lower section of a Mansard roof for a building,- an outer and inner band mold around the upper end of the building wall adapted to be supported upon the molds between which thefw'all was formed, a plurality of brackets upon the outer band mold, perforation through the outer end of each bracket, a: cornice forming shelf mounted around said outer band mold upon said brackets having an upstanding rim aroundits outer circumference, a plurality of tapering mold plates, each having means for securing one to another, arranged around the outer edge of the cornice forming shelf and Within the upstanding rim aforesaid, a rod threaded at one end and provided with a nut and havinga hook at the other end adapted to be hooked over the upper end of a tapering mold plate and be connected with a bracket through a perforation therein, and a plurality of like tapering mold plates as said outer ones aforesaid mounted upon the upper edge of the inner band mold and a ring at their upper ends inside thereof.
